2019 Assessment of Blackspotted and Rougheye Rockfish Stock Complex in the Bering Sea and Aleutian Islands

January 27, 2020

In 2018 a full assessment was conducted for the BSAI blackspotted and rougheye rockfish complex (https://archive.fisheries.noaa.gov/afsc/REFM/docs/2018/BSAI/BSAIrougheye.pdf).

In 2018 a full assessment was conducted for the BSAI blackspotted and rougheye rockfish complex (https://archive.fisheries.noaa.gov/afsc/REFM/docs/2018/BSAI/BSAIrougheye.pdf). A partial assessment is conducted this year by revising the recent catch data and re-running the projection model using the results from the previous full assessment as a starting point for the Aleutian Islands portion of the stock, with the eastern Bering Sea portion assessed with Tier 5 methods applied to survey biomass estimates. Therefore, this update does not incorporate any changes to the 2018 assessment methodology, but does update the catch estimates for 2018-2020 and provides an estimated catch for 2021. The partial assessment also includes estimates of catch/biomass (i.e., exploitation rates), using estimated total biomass.
